Today is Windows XP's anniversary: it's 4 years old now. I'm a stickler for that kind of thing, must be something to do with my youth.
What happened in those 4 years? Google came, and OSs went from first tier to second tier. Nobody cares what their PC runs on anymore, everybody just wants to go where the info is. Apple has figured this out and now makes music players and sells iTunes. I guess once Steve Jobs has got his head around computers again (you know he will - he has this cyclicity about him) he'll come up with an iPod equivalent for mailing, blogging and voicing as well.
Incidentally, 'telephony' is out. It's now called 'voicing.' Voicing is part of the communication process, which in turn is dominated by those who provide access to information. Google, Yahoo, and Apple are the stars of the moment. Telcos are the dogs. Microsoft and Cisco are the plumbers, so they won't have to worry about losing their job. It's just goodbye to the limelight.
So by the time Windows Vista finally arrives, OS launches have become non-events. Guess I won't have to make note of the launch date, then. Hasta la Vista, baby.
